This library is deprecated. If you think it's important to maintain this library, please submit an issue and the case will be consider or the repo / ownership will be transferred to you. Viable alternatives:
- Use Browserify
- https://www.npmjs.com/package/sha.js (used by Browserify)
npm install --save sha256
Note: when Node.js is detected, the Node
Crypto component is used instead of re-implementing the SHA256 hash logic.
There are two methods, one for computing the hash of the input, and one for double-hashing it:
; // "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"sha256; // "d7914fe546b684688bb95f4f888a92dfc680603a75f23eb823658031fff766d9"
Input is either an array of bytes or a string. String are always interpreted as binary data; if you have a hex-encoded string of data to parse, first convert it to a binary string or array of bytes.
Output by default is a hexadecimal-encoded string. Other options are an array of bytes, or a binary-encoded string:
; // "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824" <= Hex-encoded; default; // [44,242,77,186,95,176,163,14,38,232,59,42,197,185,226,158,27,22,30,92,31,167,66,94,115,4,51,98,147,139,152,36] <= Array of bytes; // ",òMº_°£&è;*Å¹â\§B^s3b$" <= Binary-encoded string
Unit tests are written in Mocha. To run the test suite, checkout the git repository, and from within the base folder run:
$ npm install --dev$ npm test
